Splitting and making explicit the de Rham complex of the Drinfeld space

Christophe Breuil, Zicheng Qian

Let $p$ be a prime number, $K$ a finite extension of $Q_{p}$ and $n$ an integer $\geq 2$ . We completely and explicitly describe the global sections $I^c ◯^{∙}$ of the de Rh…

On generalization of Breuil--Schraen's $L$ -invariants to $GL_{n}$

Zicheng Qian

Let $p$ be prime number and $K$ be a $p$ -adic field. We systematically compute the higher $Ext$ -groups between locally analytic generalized Steinberg representations (LAGS…

On $Ext^{∙}$ between locally analytic generalized Steinberg with applications

Zicheng Qian

Let $n \geq 2$ be an integer, $p$ be a prime number and $K$ be a finite extension of $Q_{p}$ . Motivated by Schraen's thesis and Gehrmann's definition of automorphic simple $\…
